I called livernois about 1030 and they had it ready to picked up at 1200! I loaded the 87 performance octane tune in the parking lot. I'm pretty impressed with the power difference. It's not drastic but it's there. But let me tell you about the shifting, WOW!! It shifts so nice. It's quick and firm. Thanks livernois!

Can't wait to load the 93!

I'm jealous, that's one of the next things I want to do, along with their highflow cat y pipe.

Wait till you load the 93v2, it blows the doors off the 87 tune. The 93v2 tune just spools so fast.

Ya I'm excited. I got 87P/T and 91P and 93P

93 Perfomance V2 and a CAI has gotten me 13.60 @98.21mph at Milan with some room for improvement. That's some power moving a 6000 lb brick.

I've noticed even without the tuner when I hammer down from like 60 and it downshifts it take off like a rocket but when it finds that next gear it shutters. It kind of feels like a tranny issue or axle wrap.

Did you ever check your plugs twin?

TwinTurboFx4

yup gapped them down a bit to .032. I almost postive that wouldnt be the issue. I want to say it feels more like a axle wrap issue. because I know the transmissions in these trucks are very strong. I need to get my brother inlaws go pro and some how mount it underneath for a look when im driving.

When mine axle wraps you know it...like jar your teeth shaking. Could be some tho. I took the block out of the back to see if it made a difference for the track as it was hard to do much of a burnout (and I don't do it hard just clean the tires as the return road is full of pebbles and sand) and it helped. I have to raise it back up as its killing me lol, thinking about adding a leaf pack instead of the block.
